Is having a birth certificate of tamilnadu enough for me to get into a medical college in tamilnadu?or is it a must to do my schooling there

According to the eligibility criteria you need to either live in the city, or should have completed your schooling from class 6th to 12th from the state or if you belong to state but had done your schooling from any other state you cab simply provide them you native certificate, or your parents certificate. I request you to make a native certificate as there could be some problem with the birth certificate because ut isn't not a valid proof that your parents or you belong to the state.

You can get all other information regarding eligibility criteria on the link given below.
